* using {@code int} arithmetic, where {@code s[i]} is the * <i>i</i>th character of the string, {@code n} is the length of * the string, and {@code ^} indicates exponentiation. * (The hash value of the empty string is zero.) * * @return a hash code value for this ob...
the fields of Debian Packages and Sources files was used, and each hash function was run 1,000,000 times for each word. The byte count of the words were then summed up and divided by the total number of nanoseconds each function ran, so all speeds below are given in bytes per nanosecon...
The usual mitigation is to check the buffer alignment either in the caller, provide a pre-processing loop for the misaligned prefix, or copy the whole buffer into a fresh aligned area. Put that extra code inside #ifdef HAVE_ALIGNED_ACCESS_REQUIRED. oob - Out of bounds Some hash function as...
LintCode-Hash Function In data structure Hash, hash function is used to convert a string(or any other type) into an integer smaller than hash size and bigger or equal to zero. The objective of designing a hash function is to "hash" the key as unreasonable as possible. A good hash ...
(2)然后它的底层会调用K的hashCode()方法得出hash值。 (3)通过哈希表函数/哈希算法,将hash值转换成数组的下标,下标位置上如果没有任何元素,就把Node添加到这个位置上。如果说下标对应的位置上有链表。此时,就会拿着k和链表上每个节点的k进行equal。如果所有的equals方法返回都是false,那么这个新的节点将被添加到链...
In this research, the development of an obfuscator that can work on C language source code uses the code transposition method, namely randomizing the arrangement of lines of code with a hash function and then using the DES encryption algorithm to hide the parameters of the hash function so ...
This allows users to test the code with no visible behavior change except for performance. This allows running even tests that assume the SHA-1 hash function, to sanity-check the behavior of the new mode. ("early transition") Allow both SHA-1 and SHA-256 object names in input. Any ...
